1.Analysis of procalcitonin,C-reactive protein concentration and WBC count in patients infected by different bacteria
International Journal of Laboratory Medicine 2014;(17):2301-2302
Objective To investigate the concentration of procalcitonin,C-reactive protein and WBC count for patients with dif-ferent kind of bacterial infection.Methods 49 blood samples and 81 other samples were collected form different patients for bacteri-al culture.Meanwhile,procalcitonin,C-reactive protein concentration and WBC count of those patients were determined to find whether these indicators exhibited any difference between Gram-positive and Gram-negative bacteria infected patients.Results For bloodstream infection,PCT levels in patients with Gram-nagetive bacterial infection were obviously higher than those with Gram-positive infection(P <0.05 ).For other infection,there was no statistical difference among patients′PCT,CRP concentration and WBC count(P >0.05).Conclusion PCT concentration is valuable in the differential diagnosis of blood stream infection caused by Gram-negative and Gram-positive bacteria,but not in local infection infection.

There are approximately 240 million patients with chronic hepatitis B virus (HBV) in the world.Despite the production of HBV vaccines and antiviral drugs, HBV still remains a serious threat as an infectious disease to human health.Due to the lack of an ideal animal model, the study of HBV is limited.This review was to analyze in accordance with existing HBV animal model, to explore the differences in applications of various models regarding their etiology, pathology and pathophysiology.thus, to provide a reference for researchers in future HBV research to better use the resources.

Objective To investigate the distribution and antimicrobial resistance of clinical bacterial strains isolated from the cervical secretions of parturient women .Methods A total of 239 bacterial strains were isolated from 1 519 cervical specimens of parturient women .These strains were identified and tested by Kirby‐Bauer method for their susceptibility to antimicrobial agents .Results Escherichia coli was the most frequently isolated bacteria ,accounting for 34 .3% .The bacterial strains were more or less resistant to commonly used antimicrobial agents .Conclusions Various bacterial species are identified in the cervical secretions of parturient women ,primarily Escherichia coli and Staphylococcus aureus .Bacterial culture and antimicrobial susceptibility testing are important for clinicians to take appropriate measures to reduce the incidence of mother‐to‐child infections .

The main purpose of ideology and morality course is not only to pass on knowledge and theory to students but also to teach them ideology and conduct norms on the basis of knowledge and theory. The reform and exploration of teaching patterns of ideology and morality course should concentrate upon the three ways of "theory teaching, case analysis and classroom discussion", so that teachers and students can interact and cooperate with each other, serve the same teaching theme and bring into fullplay teachers' leading function and students' initiative in classroom teaching.

The medical law science interdisciplinary talents play an crucial role in solving medical service dispute and alleviating contradictory. Based on the questionnaire survey and the interview to the court and law offices as well as the analysis of the society's demand for the knowledge structure and ability of medicine law professionals, we proposed the construction of the training mode for medicine law professionals with the ability to adapt to the social demand.

Abstract: Objective To investigate the composition and diversity of midgut microbial community of Haemaphysalis longicornis infected with severe fever with thrombocytopenia syndrome virus (SFTSV). Methods The midgut DNA of three group Haemaphysalis longicornis infected with SFTSV was extracted, and the 16S rDNA gene of the sample was sequenced by HiSeq platform. The composition and diversity of endosymbiotic microbial community were clarified by OTU cluster analysis and alpha diversity analysis. Results The midgut microbial clusters of the three groups infected with SFTSV were 143, 113, 163 OTUs respectively; the sparsity curve and abundance grade curve showed that the data had sufficient sequencing depth, and the midgut of Haemaphysalis longicornis infected with SFTSV was rich in microbial composition, but the species distribution was uneven. The analysis of microbial community composition showed that Proteobacteria, Firmicutes and Actinobacteria were the main dominant bacteria at the phyla level. At the class level, Gammaproteobacteria, Bacilli, Betaproteobacteria and Actinomycetia were the main dominant bacteria. At the order level, Legionellales, Bacillales, Burkholderiales and Actinomycetales were the main dominant orders. At the family level, Coxiellaceae, Bacillaceae, Moraxellaceae and Rhodococcaceae were the main dominant families. At the genus level, the relative abundance of Coxiella was the highest, followed by Aeribaillus and Azonexus. Alpha diversity analysis showed that the average Shannon index was 139.67, the average Simpson index was 0.48, the average Chao index was 145.06, and the average ACE index was 147.11. Conclusions The species diversity of intestinal microorganisms in Haemaphysalis longicornis infected with SFTSV is rich. The results provide a basis for further exploring the interaction between intestinal microbes of Haemaphysalis longicornis and SFTSV and developing new ideas for the prevention and control of ticks and tick-borne diseases.

Artemisia lactiflora is an important medicinal plant in China. The antitumor and antioxidant activities of the extracts of 54 endophytic fungi from the plant were screened via MTT assay and DPPH scavenging radical assay, respectively. The bioactive strains were identified based on similarity of 5.8S gene and internal transcribed spacer (ITS) sequences. The results showed that extracts from ten (18.5%) isolates exhibited antitumor activity, and which from two (3.7%) isolates exhibited antioxidant activity. The Alternaria sp. GYBH47 strain was simultaneously having antagonistic activity against HL-60 leukemia, MCF-7 breast and COLO205 colon cell lines, and Phomopsis sp. GYBH42 strain having cytotoxic and antioxidant activities. The results indicated that endophytic fungi from Artemisia lactiflora are potential resources to find valuable bioactive components.
